The Eastern Railroad was a railroad connecting Boston, Massachusetts to Portland, Maine. Throughout its history, it competed with the Boston and Maine Railroad for service between the two cities, until the Boston & Maine put an end to the competition by leasing the Eastern in December 1884. Much of the railroad's main line in Massachusetts is used by the MBTA's Newburyport/Rockport commuter rail line, and some unused parts of its right-of-way have been converted to rail trails.
